Problems in ferry services due to strong winds
Strong winds reaching up to 10 Beaufort in many areas have caused problems in ferry services on Friday.
Ships at the ports of Piraeus, Rafina and Lavrio to Crete are docked.
There is also no service for Aghia Marina-Nea Styra Kea, Rio-Antirio and Kyllini-Zakynthos.
Passengers planning to travel are advised to contact the local port authorities or travel agencies before setting off.
